A boom barrier is a physical security device commonly used in traffic management and access control systems. It consists of a horizontal bar or pole, known as the boom, which can be raised or lowered to control the passage of vehicles. Typically installed at entry points such as toll booths, parking lots, or secure facilities, boom barriers act as a barrier to regulate the flow of traffic. These barriers can be manually operated, where an attendant controls the boom, or automated with the use of electronic systems.In automated boom barrier systems, various technologies such as sensors, RFID cards, or remote controls are employed to manage access. When a vehicle approaches the barrier, the system detects the authorized credentials and automatically raises the boom to allow passage. Conversely, if unauthorized access is detected or there's a security concern, the barrier remains closed. Boom barriers play a crucial role in enhancing security, preventing unauthorized entry, and streamlining traffic at checkpoints, making them an integral component of modern access management solutions.
